Members of the Amish community leave the U.S. Federal Courthouse Thursday, April 19, 2012, in Cleveland. Sixteen men and women have pleaded not guilty in beard- and hair-cutting attacks against fellow Amish in Ohio. A feud over church discipline allegedly led to the attacks, in which the beards and hair of men and hair of women were cut. (AP Photo/Tony Dejak)
